I served as a consultant, guiding the complete redesign of their parking and electric vehicle charging IoT systems — from the hardware level to system monitoring and management.

This is a passion project currently in its early stages, built on the foundation of expertise I've gained over years of experience in the parking industry.

A simple visualization project became a breakthrough in file analysis, reducing the count and sum of a thousand terabytes of small files from 2 days to 4 hours.

A colleague from Rollet and I built a solar-powered sensor for agriculture, using LoRa and sleep cycles for efficient long-range data transmission.

I joined Rollet as a full-stack developer during its early startup phase. Over time, I focused more on IoT and monitoring. Later, I returned as a contractor, working exclusively on IoT and embedded systems, including a ticket kiosk system.

I developed the company's internal HR system, working largely independently on the technical side while also contributing to product development.
